Webpacker 清单为空，样式在

问题描述

当我尝试从部署在 Heroku 上的网站访问页面时，出现错误：

ActionView::Template::Error (Webpacker can't find application.js in /app/public/packs/manifest.json`

这是它向我展示的解决方案：

1. You want to set webpacker.yml value of compile to true for your environment
unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
}
):
8:     <%= stylesheet_pack_tag "application",media: 'all','data-turbolinks-track': 'reload' %>
9:     <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.2/css/all.css">
10: 
11:     <%= javascript_pack_tag 'application','data-turbolinks-track': 'reload' %>
12:     <script src="https://js.stripe.com/v3/"></script>
13: 
14:     <%= favicon_link_tag asset_path('favicon.ico') %>

令我惊讶的是清单中似乎有一些东西，但它只是在括号之后添加。很想看看是否有人能告诉我这是否是这里的问题以及如何解决。

解决方法

复制文件后尝试运行：

bundle exec rake assets:precompile

我正在用一个空的文件覆盖 manifest.json。
